我在我的项目中使用 restkit 我试图通过以下方式设置解析器的配置
：
[[RKParserRegistry sharedRegistry] setParserClass:[RKJSONParserJSONKit class] forMIMEType:@"text/javascript"];
我在 restkit 文档中导入了解析器的库
#import <RestKit/JSONKit.h>
但总是错误
使用未声明的标识符“RKJSONParserJSONKit”
我也尝试通过从其位置导入标头来修复它：
#import <RestKit/Code/Support/Parsers/JSON/RKJSONParserJSONKit.h>
它不起作用，但是当我尝试复制解析器所需的文件并将其作为文件添加到我的项目中时，liker 给了我：
